Lincoln magnum chiller

I check my welder for dust and the cooler for water level alot.......Probably just a habit I acquired through the years but I guess it's a good habit.....Well I noticed a "Squeak" noise coming from the cooler and I had some time so I took the cover off this morning and found that the nylon fan had lost it's fit on the motor shaft and was slipping (Not turning) I took the motor out of the cooler frame and saw that the motor shaft had a flat spot on it for like a set screw ? evidently the fan is glued on from the factory with a small clamp that holds the fan on the shaft along with the glue I cleaned everything up and mixed up some JB Weld and glued the fan back on.....
Must have worked because the squeak went away..... weird

Re: Lincoln magnum chiller

The nylon might have originally had a molded hump inside the hole to match the flat. Lots of modern small 'plastic' fans have just a spring band on the hub to create enough friction to keep it tight on the shaft; some have both that and the lump. Sometimes when epoxy wont stick to plastics, first coating the plastic with cyanoacrlate (e.g. superglue or equivalent) will allow better adhesion.

I figure if I start hearing the squeak again I'll go with super glue....
